FLUE=CLEANER.

SPECEEICATON forming part of Letters Patent No. 307,855, dated November 11l 1884.

Application filed May 23, 1884.

.To a/ZZ whom t may concern,.-

Be it known that I, JAMns HAUGHAN, of Niagara Falls, in the county of Niagara and State of New York, have invented certain new and useful Improvements in Flue-Cleaners; and I do hereby declare that the following description of my said invention, taken in connection with the accompanying sheet of drawings, forms a full, clear, and exa-ct specification, which will enable others skilled in the art to which it appertains to make and use the same.

My present invention has general reference to improvements in flue-cleaners for steamboilers; and it consists, essentially, in the novel and peculiar combination of parts and details of construction, as hereinafter first fully set forth and described, and then pointed out in the claims.

In the drawings already mentioned, which serve to illustrate my said invention more fully, Figure l is a side elevation, and Fig. 2 a longitudinal sectional elevation, of my iinproved boiler-flue cleaner.

Like parts are designated by corresponding letters of reference in all the figures.

The object of my present invention is the production of a combined steam-and-air luecleaner in which the steam shall be used as a means for forcing a current of heated air through the flues, toremove the deposit in the same, substantially as hereinafter mentioned. To attain this result I construct my flue-cleaner essentially of a T, A, having in its branch a a nozzle or other tting to which is secured a steam-hose, H, to convey steam to the cleaner. Into one of the through7 branches of this T is screwed a suitably-sized pipe, B, having on its upper end the conical or iiaring iiange E, and into the opposite branch are screwed two smaller-sized pipes, C D, respectively, the former of which passes through into the pipe B, while the latter, D, projects from the T A a suitable distance, and it is provided on its end with a funnel or cone, F, similar to the cone E. The pipe G is somewhat shorter than the pipe B, and in order to perfectly center it within the latter said pipe B is provided with one or more adjustingscrews, 2) passing through the wall of said pipe B and bearing against the wall of the pipe G.

(No model.)

The pipe C is sufficiently smaller in external diameter than the internal diameter of the outer pipe, B, so as to produce an annular space or passage, G, through -which the steam entering the T A through the hose H may pass and escape at the Vdischarge-opening e of the pipe B.' In escaping from said dischargeopening at the speed due the pressure of steam in the boiler the current of said steam causes a suction in the central pipe, C, and a current of air to pass through said central pipe, which air, commingling with the steam, is the medium for cleaning the flues, said current of steam and air being, as practical tests have demonstrated, fully as effective in cleaning the flues as if steam alone had been used, the quantity of the latter, however, being much smaller in the present instance, for the probable reason that the steam is used as a medium only to propel the air at the proper speed. The steam contained in the space G heats the pipe C, and that in turn heats the air-current sufiiciently to prevent serious chilling of the boiler-dues. In fact, the heat of current of mixed steam and air is but little below the temperature of the boiler-rines. The coneshaped flange E acts as a plug for the boilerues, to prevent the escape of steam toward the operator, said flange E being suiiiciently large on its largest diameter and small enough on its smallest part to lit all the various sizes of boiler-flues now in common use, so that one of these apparatus is all th at is required for manufacturing to supply the market, which is quite an advantage over Hue-Scrapers, which usually accommodate but 011e, or, at best, bu-t a few sizes of flues. The funnel shaped fitting F on the end of the pipe D acts as a concentrator for the air entering said pipe D, and thereby materially assists in supplying a large volume of air to the-apparatus.

It will be readily observed that the apparatus is readily handled by holding it by the pipe D, which, owing to the continuous current of cold air passing through it, is always kept at a very low temperature, the heat of the fitting A and pipes B G being incapable of being conveyed to said pipe D in view of the cold-air current heretofore mentioned.

rlhe entire apparatus as heretofore described can be very cheaply manufactured IOO and sold at a low iigure, and is a very desirable article to manufacture in View of its simpleity of construction and fewness of its parts.

Having thus fully described my invention, I claim as new and desire to secure to me by Let ters Patent of the United States of Amerieal. As an improved artiele of manufacture, a iiue-eleaner having` steam and air passages constructed to operate in the manner subst-antially as and for the objeet stated.

2. The improved fine-cleaner hereinbefore described, consisting, essentially, ofthe T A, having the jacket pipe B, internal smaller pipe, C, the pipe D, cone E, funnel F, and the steam-supply H, the whole being constructed and combined substantially in the manner as and for the use and purpose specified,

3. The combination, in line-cleaners having Attest:
